Question about IBM 6400 Matrix Printer

IBM 6400 missing decimal...


My first post - this site seems quite good.

Please see attached document...

Note the digits under Credits column. Its supposed to appear as the digits under the Charges column. The decimal is missing and the spread between the dollar and cents values seem bigger than normal. All numbers that in the Credits column appear uniformly like this.This happened suddenly with no fading preceding the issue.

I replaced the ribbon and did some

Any help is appreciated.

Is there print missing??? if so the hammer fret in that location probably (90%) needs cleaning as dirt can get between the fret, it only takes the smallest amount of debris to stop fret working, you need to remove hammer bank to do this, fairly simple to do just lots of screws. the only thing to check when reinstalling hammer bank is that you pull it towards you ( front of printer ) before tightening the 3 screws, this is to be sure the gap between hammer bank and platen is roughly correct. there are 2 small grub screws at each end of platen to adjust this gap if you need to.

What driver are you using for the printer?

Also, when you go to print the document, you will see a printer listed on the top of the print menu screen.

Next to that, there will be a down arrow. Click on the drop down arrow and select the IBM InfoPrint printer you want.

Wont print on line

You may need to have some driver installed on your PC, that can be downloaded from some IBM printer web site, such as this one:

IBM does not manufacture printers any more, they outsourced that to other places like Lexmark & ProPrinter, so we have to figure out which outsource place is relevant & what name they have for whatever corresponds to 6400 driver.

IBM 6400 firmware resetting

Hold cancel+stop while powering on the printer to enter the maint menu. You can wipe the firmware from there. You need to have a copy of the microcode firmware to reload. If you are uncertain about these instructions, you absolutely should not attempt it.

IBM 6400 model i10 print problem

It's likely a "hammer" is defective. This can be caused by
a build up of ink under the ribbon shield and/or around the hammer "fret" itself or the fret is physically broken. Remember
that this is a "shuttle" printer and each fret covers anywhere from
one to three characters depending on model. Some cover fractions of characters as well. The problem will appear as either
data missing on the left or right margin or a blank column of missing data going down the page.

A technician is required to solve all of these problems as the
shuttle assembly must be removed.
